Yes, there are many advantages to being a CPA, primarily the CPA brand. As I have explained to students and civilians over the years, people treat you differently when they find out you are a CPA. Our profession is still held in such esteem that it sets you aside from the general populace and gives one a leg up in all sorts of business, and even personal, situations.
Our designation certainly holds a lot more weight than being an MBA, or even a PhD, in a business discipline would.
The CPA brand has been invaluable in every aspect of my business career from the day I passed the exam. I have found it easier to get business loans, negotiate contracts, or be respected by almost anyone that has ever come in contact with CPAs or knows of the difficulty of attaining the certification.
